A Low-Cost Automatic Telescope and Modular Photo-polarimeter

Abstract

The low-cost Hall-sensor solution to the problem of positioning the telescope/photopolarimeter proved to be accurate and, once the installation problems were overcome, reliable. But this was not achieved without a cost in complexity of software and in requirements for a fast microprocessor. This approach can then provide a low-cost, highly reliable solution for an automated positioning system.
